This is useful particularly for back-testing purposes, such as testing a day-trading strategy within a particular period of the day or ignoring signals that fall within the given timeframe (which is useful for ignoring setups during your testing that appear while you're asleep or at work etc.)
Take it easy :)

For now, if you open the settings menu there is a new option to specify what timeframe to hide it on. For example, if you want to hide it on the 4H chart then type in "240", if you want to hide it on the Daily chart type in "D". It's disabled by default so you will need to activate it.
Good luck with your trading :) I'll let you know if I find a better way to do this.
If it could include a list of disabled times, would be even better tho :)
Right now I am using "240" only, but "240,D,W,M" would close to ideal for me.
